OIL CAN.

Application filed September 19, 1921. Serial No. 501,795.

To all 'wlw/m, t may concer/1t.'

Be it known that ToLLnr O. BAKKEN, citizen of the United States, residing at Bode, in the county of Humboldt and State of lowa, has invented certain new and useful Improvements in Oil Cans, of which the following is a specification.

This invention relates to certain newand useful improvements in an oil can and it has for its primary object to provide a lubricant container from which the contents may be ejected in very small quantities or in a steady stream at will by an operator.

A further object is to provide a flexible bottom and container by which the oil or liquid contents may be completely and entirely expressed by a single flexing of the bottom.

The invention further comprises a rigid frame structure having its lower end open for access to a flexible member constituting the bottom of the oil chamber and means within the chamber for holding said flexible bottom in its extended position.

Further the invention will be found to reside in the salient features of construction in the arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawings, wherein:

Figure 1 is a vertical section of the improved oil can, and

Figure 2 is a transverse section therethrough on line 2-2 of Figure 1.

Referring more in detail to the .accompanying drawing, the body comprises an Ament for a spout 2, and a lower cylindrical section 3 having a bottom wall 4: which is provided with a central opening 5. The lower cylindrical section of the body constitutes a housing or a cage for a cupshaped resilient or yieldable body portion 6 which is preferably constructed of rubber or a rubberized fabric and in general conforms to the section 3, being cylindrical in cross section and having a bottom wall seating on the bottom wall 4 thereof. The upper edge portion section 3 is offset inwardly, as indicated at 7, and over this offset portion, is turned the upper edge portion of the flexible cup 6 where it is securely held and clamped by the top section 1. The offset 7 not only reduces the upper edge of section 3 so as to snugly fit, with the turned over edge of cup 6, into the bottom edge or end of the top section 1 but also provides a shoulder or seat 8 for engagement by the lower edge of the top section and thereby forms a smooth and neat joint between the rigid body sections.

A shallow pan or cup of a non-flexible nature lits within the bottom of the flexible cup 6 and serves as a reinforcement'therefor as well as a shape-sustaining device. A pressure disk ofgreater diameter than the opening 5 is secured to the bottom of the cup 6 so as to normally close said opening, said cup 9 and disk 10 being secured in the presentinstance by a rivet ll passing there`-` through, as is most clearly depicted in Figure 1. A conically coiled spring 12 is arranged within the o il container and has its base or wider end seating within the pan 9 and its upper end embracing a vbend 13 formed about the outlet 14 leading to the spout 2.

ln practice, pressure is applied to the disk 10, as by the thumb of the hand holding'the can, whereupon the rigid pan structure will be forced inwardly against the compression of spring 12 and thereby express or eject the oil through the spout 2. The extent of the applied pressure will determine the quan tity of fluid to be ejected, the flexible side walls of the cup or bag 6 giving or yielding during the movement of the bottom thereof inwardly. It will be noted 'that the flexible oil container 6 may be forced well up into the top section 1 and thereby practically all of the liquid contents may be ejected or dis` placed by a single movement. `The pan 9 and disk 10 are preferably formed of metal and may readily be stamped `from. sheet stock. The pan serves as a plunger and distributes the pressure over a larger area of the contained fluid so that a corresponding increase in the flow of lubricant will result. After pressure has been released from the disl 10 the compressed spring 12 will expand and return the distorted flexible member 6 to its normal position wherein the disk 10 closes the opening 5 and thereby prevents any ingress of dirt or foreign matter that will tend to collect about the cup or bag 6 and impair its use and operation. top section snugly embraces the turned over upper edge of member 6 and provides a secure anchorage from which the flexible oil Vcontainer is suspended. The smooth joint cey The y betweeny the cam sections l and 3 obviates any corners, edges or projecting parts to be accidentally engaged and thereby result in displacing the top section` or loosening the anchorage of the cup or bag 6.

What is claimed is:

l. An oil can comprising a body section having its upper end offset inwardly and its bottom formed with a centrahopening, a flexible cup-member having` its upper edge turned. over and engaged with the offset portion of the body section, a pressure disk se# cured to the bottom of the cup-member and normally closing the bottom opening of the body section, a rigid pan secured in the bottomof the cup-member, a top section fitted over the turned over edge po-rtion of the cup-member on the body offset portion and securing thev cupemember to the latter, and a coil spring compressed between the pan and the top section for normally holding the cup member extended.

2. Anfoil. can'comprising a body rsection havingA its upper end offset inwardly and its bottom formed with a .central opening, a fiexible-cup-meinber havingits upper' edge turned over' and engaged with the offset portion of the body section, a pressure disk secured to thebottom of the cup-member and normally closing the bottom opening of the body section, a rigid pan secured in the bottom of' the cup-member, and a top section snu-glyembracing the turned over edge portion of; the cup-member for securing` tlie same to the body offset.

3. An oil `can including a body, a flexible cup-member in the body, means to suspend the upper` part of the member from the up per partk of` the body so as to cause the side walls'of. the member toextend approximately vertical and closely adjacent to the adja cent walls of the body, and a spring exerting downward tension on the bottom of the cup-member to hold the latter taut and with its side walls distended ifrom the points of suspension of the cup-member, said spring having its lower end of approximately the same `diameter as` that of' the bottom of the cup-member so as to prevent lateral movement of said spring end.

4. An oil can including a body having an opening in its bottom a flexible cup-member, means to suspend the cup-member from its upper end from the upper part of the body so as to cause the side walls of the member to lie approximately vertical and closely adjacent to the adjacent walls of the body, a pan in the cup-member seated on top of the bottom thereof and having its rim engaged with the side 'walls ofthe cup-member, Va spring seated in the pan and having `it lower convolution disposed adjacent to the rim thereof to exert downwardtension on'the cup-member and to hold the latter distended, and a plate secured to the under face of the bottom of ,theY cup-member and extending over the'opening in the bottom of the body.

5. An oil can including a sectional body, the ripper end of the lower section being off-` set inwardly, a flexible cup-member having its upper edge portion turned outwardly and downwardly and engaged with said off set end of the lower section, and the lower end of the top section being'engaged over the said out-turned edge portion the cupmember and extending parallel tothe offset part and arranged to haveits` exterior lie flush with the adjacent exterior portionfo'f 'the lower section.

6. An oil can including a body, a flexible cup-member in the body, means to suspend the upper edge portion of the member from the body so as to cause the lside walls of the member' to lie vertical, a rigid pan seated on the bottoni. of the flexible cup member and of` approximately the same diameter as the cup-member and engaged with the inner circumference' of the cup-member, and a spring seated on the pany and exerting downward tension on the cup member to hold the latter taut and with its side walls distended from the pointsv of suspension of the cupmember. y j
